Patients with temporomandibular disorder often present with acute occlusal change and properly managed with conservative treatment. If such change is caused by unusual etiology, differential diagnosis may be challenged. This article describes the diagnosis of a patient exhibiting pain and acute posterior open bite on the ipsilateral side after chewing hard food. After initial conservative treatment failed to resolve the complaint, magnetic resonance imaging was ordered and confirmed partial perforation of articular disc. Disc perforation itself is usually chronic in nature, but sudden macrotrauma may also cause the disorder. However, occlusal discrepancy caused by disc perforation is rare and seldom reported. We present a case of acute malocclusion caused by disc perforation with a review of related literature.

Objectives: This study aimed to evaluate the effects of occlusion patterns using the T-scan $III^{(R)}$ system and oral parafunctional behaviors on temporomandibular joint disorder (TMD) in female college students. Methods: A questionnaire survey assessed TMD symptoms and oral behavioral checklist (OBC) scores in 120 female college students in their early twenties. Occlusion was evaluated using the T-scan $III^{(R)}$ system. Logistic regression analysis was performed to investigate the relationship between occlusion and OBC scores based on patients' symptoms of TMD and to determine whether OBC scores were a predictor of TMD. Results: A total of 101 participants with an average age of 22 (${\pm}2.17$) years were included in the analysis. The reported symptoms of TMD were categorized as moderate (28.8%), slight (27.7%), severe (25.7%), and asymptomatic (17.8%). Occlusion was analyzed using the T-scan $III^{(R)}$ system, and the mean occlusion time was 0.42(${\pm}0.5$) seconds. The results of logistic regression analysis showed that the group that would 'clench or grind teeth' during sleep showed an odds ratio for TMD that was 8.9 times higher than that in the group without this behavior. The group that would 'hold, tighten, or tense muscles without clenching' while awake showed an odds ratio for TMD that was 21.3 times higher than that in the group without this behavior. Conclusions: We confirmed that oral parafunctional behavior affects TMD. Therefore, we would like to continue studying the diagnosis and treatment of TMD by evaluating occlusion patterns and related OBC scores.

Purpose: This study aims to examine correlation between temporomandibular disorder and oral habits that have been known to cause temporomandibular disorder with both male and female undergraduates. Methods: To figure out correlation between temporomandibular disorder and oral habits, a survey was conducted to 500 students of two universities located in Daegu Metropolitan City and Gyeongsangbuk-do, and excluding the ones unreliably answered or indicating errors, total 427 (85.4%) out of 500 questionnaire sheets were used for final analysis. Results: Female students showed higher prevalence rates than male students in temporomandibular joint pain and temporomandibular joint clicking, and students having the lip biting habit, tongue thrust habit, or bruxism habit indicated a higher prevalence rate of temporomandibular joint pain than normal students. Also, students having the tongue thrust habit indicated a significantly higher prevalence rate of temporomandibular joint clicking than normal students not having it. And about trismus, students having the bruxism habit showed a significantly higher prevalence rate than normal students not having it. Conclusion: The findings imply that oral habits like lip biting, tongue thrust, or bruxism are closely related with temporomandibular joint pain, tongue thrust influences temporomandibular joint clicking, and bruxism does affect trismus.

Background: The management of the behavior of handicapped children when providing required dental care is often a problem, whether in the dental office or in a hospital setting. Because of the high incidence of poor cooperation, many of these patients are scheduled for dental care under general anesthesia with preoperative medical assessment. The purpose of this study was to carry out a clinico-statistical survey on dental treatment for handicapped children under general anesthesia. Methods: After approval from the institutional review board, the medical records of 64 handicapped children between 1997 and 2002 were reviewed to determine the patient profiles, anesthesia management, and complications. The charts of these patients, who underwent dental examination, scaling and prophylaxis, and restoration and extraction of teeth under general anesthesia, were reviewed. Results: The mean age was 12.8 years old, and males (53%) predominated females (47%). Twenty-four patients had mental retardation, twelve had autism, six had cerebral palsy, 4 had behavior disorder, others had heart disease, convulsive disorder, etc. Sixty-two had intravenous thiopental with neuromuscular blocker, 2 had intravenous ketamine induction. Nasotracheal intubation was uneventful in 55 patients, nine had orotracheal intubation because of difficult visualization of the larynx. Twenty-one patients experienced postoperative complications in the recovery room, including epistaxis, nasal obstruction, vomiting, airway obstruction, respiratory depression. Conclusions: General anesthesia is a very effective way of completing the dental treatments for disabled children. We emphasize the need to train anesthesiologists in the care of disabled patients.

Purpose: To search the salivary factors that objectively indicate an pain in myalgia patients with temporomandibular joint disorder (TMD) and determine the possibility of the factors as pain-biomarkers. Methods: Participants consisted of pain-free 15 persons (male 7, female 8, mean age±standard deviation (SD); 26.8±16.04 years) and 45 myalgia patients with TMD (male 21, female 24, mean age±SD; 27.98±13.01 years). They were divided into a pain-free group (numerical rating scale [NRS] score 0), a mild pain group (NRS 1-4), a moderate pain group (NRS 5-6), and a severe pain group (NRS 7-10) and members of all groups were age, sex matched. Interleukin-8 (IL-8) and matrix metalloprotease 9 (MMP-9) were selected as pain biomarkers, by searching the Gene Expression Omnibus database and analyzing pain-related genes. Enzyme-linked immunosorbent assays were used to measure the concentration of IL-8 and MMP-9 in the patients' saliva. Results: IL-8 and MMP-9 levels were statistically significantly higher in pain groups than in the pain-free group. Greater differences were observed in patients with acute pain (with painful duration under 3 months) than in the control group and in female patients than in male. Conclusions: Salivary IL-8 and MMP-9 may play a role as biomarkers of myalgia in patients with TMD.

Dental treatment for the disabled should be a customized that considers the characteristics and degree of cooperation of each disabled patient. There are additional considerations during implant treatment and tooth extraction in disabled patients. Since some brain lesion disorder or cardiac disease patients may be taking antiplatelet or anticoagulant medications, it is necessary to evaluate whether these medications should be discontinued before an invasive procedure. Precautions should be taken for patients with heart valve disease considering the risk of infective endocarditis, especially during invasive dental procedures. Moreover, disabled patients may have difficulty in following instructions and cautions. There are specific considerations for each stage of implant treatment in disabled patients. In the case of patients who are in the pre- or post-transplant state, it is necessary to assess their general condition and oral disease due to the risk of infection. Since disabled patients with various systemic diseases may visit the dental clinic, it is important to understand their characteristics and treatment process in order to flexibly adjust the dental treatment plan accordingly.
